Changes needed for free online game site

IMPORTANT NOTICE: Due to the high number of people who say they can do the job and then never accept the assignment I have decided that I will accept a bid from someone who has a high feedback rating and has completed bids that are related to my posting. I would like to have the following changes made to my arcade site: 1. I want the script updated to the latest version, I will supply all the files needed. 2. I want to have a file added on my server that cannot be searched by the search engines and I want to be able to add say a hundred or so games and videos and then have some way to tell the site to automatically take a game from the file and add it to the site every hour and place it in the right assigned category and must be indexable by the search engine. 3. I want to have a basic shoutbox added to the main page so visitors can post a message on the main page to challenge other players, must be able to block bad words 4. I would like a complete site review for on page seo, no off page or web promotion only on page for proper white hat seo to improve search engine rankings. 5. Improve the speed at which the site loads by optimizing the file sizes. 6. All work done must come with a 30 day review and correction of any found errors. I want this work done asap so I am only going to accept bids for up to 48 hours and I will place the agreed upon price into escrow right away, I will release payment upon completion of the work with the understanding that I have 30 days from date of payment acceptance to report any errors I find on the site and have them correct by you at no additional charge. If you can complete the above work within the required time frame and can show good feedback then please respond to this posting. Thank you, Abbadox
